Malaria in Pregnancy in Endemic Regions of Colombia: High Frequency of Asymptomatic and Peri-Urban Infections in Pregnant Women with Malaria.

Background: Malaria in pregnancy (MiP) has been associated with adverse pregnancy outcomes. There is limited information on MiP in low transmission regions as Colombia. This study aimed to describe the epidemiology of MiP through active surveillance of infections by microscopy and polymerase chain reaction (PCR). Methods: A cross-sectional study was conducted between May 2016 and January 2017 in five municipalities (Apartadó, Turbo, El Bagre, Quibdó, and Tumaco) in Colombia. Pregnant women self-presenting at health centers for antenatal care visits, seeking medical care for suspected malaria, or delivery, were enrolled. Diagnosis of Plasmodium spp was made in peripheral and placental blood samples by microscopy and PCR. Results: A total of 787 pregnant women were enrolled; plasmodial infection was diagnosed by microscopy in 4.2% (95% CI 2.8-5.6; 33/787) or by nPCR in 5.3% (95% CI 3.8-6.9; 42/787) in peripheral blood. Most of the infections were caused by P. falciparum (78.5%), and 46% were afebrile (asymptomatic). Women in the first and second trimester of pregnancy were more likely to be infected (aOR = 3.06, 95%CI = 1.6 - 5.8). To live in the urban/peri-urban area (aOR = 3.04, 95%CI = 1.4 - 6.56), to have a history of malaria during last year (aOR = 5.45, 95%IC = 2.16 - 13.75), and the infrequent bed net usage (aOR = 2.8, 95%CI = 1.31 - 5.97) were associated with the infection. Pregnant infected women had a higher risk of anaemia (aOR = 2.18, 95%CI = 1.15 - 4.12) and fever (aOR = 14.2, 95%CI = 6.89 - 29.8). Conclusion: The screening for malaria during antenatal care in endemic areas of Colombia is highly recommended due to the potential adverse effects of Plasmodium spp. infection in pregnancy and as an important activity for the surveillance of asymptomatic infections in the control of malaria.

Successful treatment of cutaneous leishmaniasis with intralesional meglumine antimoniate: A case series.

Cutaneous leishmaniasis (CL) is a high-morbidity, vector-borne disease endemic to Colombia. Unlike conventional systemic antileishmanial therapy, intralesional meglumine antimoniate administration has fewer adverse effects and can be as effective and safe. We describe 12 patients treated with intralesional meglumine antimoniate: seven with primary and five with recurrent lesions. The majority (11/12) met all cure criteria after 1-7 sessions of meglumine antimoniate administration (1-5 mL). Adverse effects comprised mainly of local pain and edema. Intralesional meglumine antimoniate administration could be an excellent alternative treatment for uncomplicated CL; however, controlled clinical trials are needed to test the efficacy and safety thereof.

[Clinical and laboratory profile of Plasmodium vivax malaria patients hospitalized in Apartadó, Colombia]. / Perfil clínico y de laboratorio de los pacientes con malaria por Plasmodium vivax, hospitalizados en Apartadó, Colombia.

INTRODUCTION: Malaria is a public health problem in the Urabá region recording rates of infection above those of the Antioquia department. The burden of vivax malaria is 78.7% and the profile of vivax malaria in this region has scarcely been studied. OBJECTIVES: To analyze the clinical and laboratory characteristics of patients hospitalized for vivax malaria in Apartadó. MATERIALS AND METHODS: We reviewed the medical records of patients with vivax malaria hospitalized in the Antonio Roldán Betancur hospital from 2004-2007. Results. Of 359 patients with vivax malaria who required hospitalization, 23.1% (83/359 patients) had the following complications: severe anemia, 51.8% (43/83); severe thrombocytopenia, 15.6% (13/83); hyperbilirubinemia, 7.2 % (6/83). Some patients met several criteria for complicated malaria simultaneously, including one case of acute respiratory distress syndrome. The most significant laboratory changes were decreases in the hemoglobin, hematocrit and platelet levels, with increased levels of transaminases and bilirubin. Only 4.82% (4/83) of patients with complicated malaria were treated with intravenous quinine, no one died. CONCLUSIONS: The elevated frequency of complicated vivax malaria found in the Uraba region in this study is noteworthy, particularly in children under 5 years. The results highlight the need to strengthen, amongst the health staff, the knowledge of the guidelines for the clinical care of malaria patients, in order to make a correct clinical diagnosis and provide appropriate treatment.

Perfil clínico y de laboratorio de los pacientes con malaria por Plasmodium vivax, hospitalizados en Apartadó, Colombia / Clinical and laboratory profile of Plasmodium vivax malaria patients hospitalized in Apartadó, Colombia

Introducción. La malaria representa un problema de salud pública en la región de Urabá, donde se registran tasas superiores a las del departamento de Antioquia; la carga de malaria por Plasmodium vivax es de 78,7 % y poco se ha explorado su perfil en la región. Objetivos. Con el presente estudio se pretende conocer las características clínicas y de laboratorio de los pacientes hospitalizados por malaria por P. vivax en Apartadó. Materiales y métodos. Se revisaron las historias clínicas de pacientes con malaria por P. vivax que requirieron manejo hospitalario en el Hospital “Antonio Roldán Betancur”, Empresa Social del Estado, durante los años 2004-2007. Resultados. Se hospitalizaron 359 pacientes con malaria por P. vivax, de los cuales, el 23,1 % (83/359 casos) se complicó por anemia grave (51,8 %, 43/83), por trombocitopenia grave (15,6 %, 13/83) y por hiperbilirrubinemia (7,2 %, 6/83); algunos pacientes satisfacían varios criterios simultáneamente, incluyendo un caso de síndrome de dificultad respiratoria aguda. Los datos de laboratorio más significativos mostraron disminución de los niveles de hemoglobina, hematocrito y plaquetas, con aumento en los niveles de transaminasas y bilirrubinas. Sólo el 4,82 % (4/83) de los pacientes con malaria complicada, recibió tratamiento con quinina intravenosa, ninguno falleció. Conclusiones. Se destaca en este trabajo la frecuencia importante de malaria complicada por P. vivax, particularmente en los menores de cinco años, en la región de Urabá, y la necesidad de fortalecer el conocimiento de la guía para la atención clínica integral del paciente con malaria, entre el personal de salud, para hacer un diagnóstico clínico correcto y ofrecer el tratamiento apropiado.
